写在前面

需求

备份系统日志表T_S_LOG, 按照操作时间字段OPERATETIME, 将每天的日志增量备份到另一张表.

思路

1.创建一张数据结构完全相同的表T_S_LOG_BAK作为备份表

2.查出T_S_LOG中需要备份的数据

3.将数据赋给游标变量

4.遍历游标将数据逐条插入T_S_LOG_BAK

5.创建无参存储过程将游标的这部分操作作为存储过程主体执行

6.创建定时任务定时执行该存储过程

操作环境

Oracle11g

操作步骤

1.创建备份表(上面贴了)

2.声明游标,定义记录变量接收查询出的数据,遍历记录插入到备份表,关闭游标

技术图片
 1 declare
 2   --定义游标
 3   cursor cursor_log is
 4     select * from t_s_log where to_char(t_s_log.operatetime,yyyyMMdd) = to_char(sysdate,yyyyMMdd);
 5   --定义记录变量
 6   ls_curinfo cursor_log%rowtype;
 7 begin
 8   open cursor_log;--打开游标
 9   loop
10     FETCH cursor_log
11       INTO ls_curinfo;--获取记录值
12     EXIT WHEN cursor_log%NOTFOUND;
13    insert into t_s_log_bak(ID,
14       BROSWER,
15       LOGCONTENT,
16       LOGLEVEL,
17       NOTE,
18       OPERATETIME,
19       OPERATETYPE,
20       USERID,
21       USERNAME,
22       REALNAME) values(ls_curinfo.ID,
23       ls_curinfo.BROSWER,
24       ls_curinfo.LOGCONTENT,
25       ls_curinfo.LOGLEVEL,
26       ls_curinfo.NOTE,
27       ls_curinfo.OPERATETIME,
28       ls_curinfo.OPERATETYPE,
29       ls_curinfo.USERID,
30       ls_curinfo.USERNAME,
31       ls_curinfo.REALNAME); commit;
32   end loop;
33   close cursor_log;--关闭游标
34 end;
View Code

到这里测试没什么问题就继续创建存储过程

3.创建无参存储过程

存储过程不细说了,大致结构就是:

CREATE OR REPLACE 
procedure 存储过程名字 as
begin
...(过程体)...
end;

过程体就是第2步定义的游标及遍历那部分直接粘过来就可以了

完整的存储过程如下:(这里用Navicat执行时遇到点问题, 改为PL/SQL执行没问题, 不太清楚是什么操作)

技术图片
 1 CREATE OR REPLACE 
 2 procedure procedure_log_bak as
 3 begin
 4   declare
 5   --定义游标
 6   cursor cursor_log is
 7     select * from t_s_log where to_char(t_s_log.operatetime,yyyyMMdd) = to_char(sysdate,yyyyMMdd);
 8   --定义记录变量
 9   ls_curinfo cursor_log%rowtype;
10 begin
11   open cursor_log;--打开游标
12   loop
13     FETCH cursor_log
14       INTO ls_curinfo;--获取记录值
15     EXIT WHEN cursor_log%NOTFOUND;
16    insert into t_s_log_bak(ID,
17       BROSWER,
18       LOGCONTENT,
19       LOGLEVEL,
20       NOTE,
21       OPERATETIME,
22       OPERATETYPE,
23       USERID,
24       USERNAME,
25       REALNAME) values(ls_curinfo.ID,
26       ls_curinfo.BROSWER,
27       ls_curinfo.LOGCONTENT,
28       ls_curinfo.LOGLEVEL,
29       ls_curinfo.NOTE,
30       ls_curinfo.OPERATETIME,
31       ls_curinfo.OPERATETYPE,
32       ls_curinfo.USERID,
33       ls_curinfo.USERNAME,
34       ls_curinfo.REALNAME); commit;
35   end loop;
36   close cursor_log;--关闭游标
37 end;
38 end;

到这里手动执行存储过程也没问题就继续创建定时任务,即Oracle的job

4.创建定时任务

使用PL/SQL找到DBMS_Jobs右键New...不细说了,可以移步https://www.cnblogs.com/yx007/p/6519544.html这篇讲的很详细,这里主要记录一下创建完成后遇到的问题.当创建完成后job并没有执行,Last_date这个字段是空的, 并且Next_date并不是job定义的执行时间.

技术图片

 

 到这里需要手动执行job:

技术图片

 

 执行之后last_date字段有值了,而且next_date的值也是想要定义的job执行时间了

技术图片

 

 到这里就没什么问题了.
